would be nice to put Maple Pro running on my USB to be able to start it also from other PCs everywhere in the world. But I don't want to have my key in the registry of other persons PCs, so it would be nice, if there would be also a "ini" (or "xml") mode to be fully portabel!

Another thing would be to compress all executable parts as much as possible so it does not need so much space on the USB device. I'll tried to do so with UPX 2.01, but it seems, that all files have already been packed - but maybe UPX would do a better compression?!
